Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a kana-kanji conversion apparatus and method for converting a character string of a kana expression into a sentence mixed with kana-kana.

(Conventional technology) Conventionally, a method of inputting a kana character string to a kana-kanji conversion device includes a method of inputting a kanji for each kanji (single kanji conversion method), a method of inputting each phrase (phrase input conversion method),
There is a method (solid input method) for inputting kana character strings regardless of kanji or phrases. Of these, solid input methods have become mainstream in recent Japanese word processors. This solid input method is convenient because you don't have to worry about kanji or phrases when inputting. However, on the other hand, you can enter a document without pressing the conversion key, so if you make a mistake and input too long, the part will be converted to unexpected kanji, so the mistake will be displayed on the display screen. There was a problem that it was difficult to discover. Further, since the conversion is performed sequentially without pressing the conversion key, there is a problem that there is no means for the input user to know how the input sentence is analyzed in the word processor.

(Problems to be Solved by the Invention) As described above, the solid input method adopted in Japanese word processors in recent years is convenient, but when inputting a long document, it is difficult to confirm the input characters later. If there is a mistake, the conversion is made based on the incorrect input character string, and it is difficult to correct it.

Also, I don't know how the Kana-Kanji conversion part cuts the input Hiragana character string,
The input user remained uneasy during the conversion.

In view of this point, the present invention makes it easy to find a mistake in the input kana character string, and if there is an error in the kana-kanji conversion section for the input kana character string, remove it before conversion. A kana character string display correction method that can be corrected is provided.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above problems, the kana-kanji conversion method of the present invention firstly analyzes the input of a kana character string and obtains the analysis. The phrase segmentation information is explicitly displayed by inserting a blank, a slash, or a special segmentation code into a character string.

Secondly, the present invention is characterized in that the character string displayed by the means is provided with a means for re-cutting the character string when the input person notices that the segmentation is incorrect.

(Operation) According to the present invention, the input user can quickly and accurately grasp whether or not an input character is incorrect, and can correct an error when there is an error.

FIG. 1 is a block diagram showing an embodiment of the present invention.
In the figure, 1 is a kana input unit, 2 is a phrase recognition unit, 3 is a phrase segmentation correction unit, 4 is an input kana character display unit, 5 is a kana-kanji conversion unit, and 6 is a conversion result display unit.

The kana character string input from the kana input unit 1 is sequentially sent to the phrase recognition unit 2 to recognize phrase separation by means such as the longest match method. The input kana character display section 4 displays the input character string and its segmentation. At this time, if an error occurs in the segmentation, the segmentation modification unit 3 corrects the segmentation through the segmentation processing from the input user. After the correction, the kana-kanji conversion unit 5 performs the kana-kanji conversion process using the segmentation information, and the conversion result display unit 6 displays the obtained result.

FIG. 2 is a flowchart of the phrase recognition unit. Whenever one Kana character is input, if the phrase that has not been converted can be segmented after the input character, flag =
Set to 1 and output the input character as it is. When segmentation is impossible and flag = 1, the input character is output after inserting a segmentation code, and flag = 0.
If phrase separation is not possible and flag = 0, the input character is output as it is. If the user notices an error in segmentation, the segmentation correction unit re-segments the segmentation. This operation is sequentially repeated, and when the number of input characters reaches the designated number of phrases, or when "." Or "," is input, the kana-kanji conversion unit 5 performs the kana-kanji conversion process based on the segmentation.

FIG. 3 is a flowchart relating to a segmentation correction unit. Activated by pressing the cursor key, segmentation key, or delete key.The cursor moves when the cursor key is depressed, and inserts or deletes the segmentation code below the cursor when the segmentation key is depressed. If it is a key, delete the character under the cursor (including the segmentation code).

FIG. 4 is an example of the case where the user actually wants to input "Please take off your shoes here." However, here, it is assumed that the conversion is started when three phrases have been reached. When the first character "ko" is entered, "ko" is not a particle, so the phrase cannot be cut after "ko". Therefore, flag = 0 remains. The same applies to the next “ko”. The next "de" is a particle and "here" is a single word, so that the possibility of segmentation occurs after "de" and flag = 1. However, since "wa" becomes a particle at the stage of inputting "wa", there is a possibility of segmentation and flag = 1 again. However, at the stage of inputting "ki", "ki" is not a particle and is not a particle even if it is combined with the preceding character. Therefore, after "ki", segmentation becomes impossible, and flag = 1 Therefore, segmentation will occur before "ki". Therefore, the display is as shown in 4-4.

Thereafter, the same processing is sequentially performed up to 4-6. However, the phrase segmentation shown in 4-6 is different from the desired phrase segmentation "Please remove the footwear here." Here, by moving the cursor, the cursor is moved over the segmentation code between “ha” and “ki” (4-
7) Press the delete key to delete the segmentation code (4-8). Also, the cursor is moved over "ha" (4-9), and a phrase separation code is inserted by pressing a phrase separation key (4-10). Then, if you return the cursor to the input key again (4-11), you can enter the rest,
When "ku" is entered, three phrases are recognized, so they are automatically converted (4-12). Thereafter, conversion is performed at the stage when "." Is input, and a final conversion result is obtained (4-13). Also,
In the case of this example, the same effect can be obtained even if the segmentation code is moved by the movement key.

[Effects of the Invention] As described above, according to the present invention, a user can perform an input operation while easily determining whether or not an input kana character string is correct in solid writing conversion.
Also, since the word processor's segmentation for the input character string is explicitly shown, if it is not what the input user expects, correct that segmentation and convert it with the correct segmentation information It becomes possible. Also,
At the stage where the input character string has not been converted, it is easy to detect and correct an input error.
